Human Secretory Leukocyte Peptidase Inhibitor (SLPI) ELISA Kit

Secretory Leukocyte Peptidase Inhibitor (SLPI) is a 12 kDa serine protease inhibitor secreted by epithelial cells at mucosal surfaces, where it neutralizes neutrophil elastase, cathepsin G, and trypsin released during inflammatory responses. The Assay Genie ELISA Kit enables quantitative measurement of this innate immunity protein in human samples, supporting research into chronic inflammatory diseases, respiratory disorders, and epithelial barrier function.

Configured for 96 assays on a microplate format, the kit is intended for in vitro research use only. Each kit provides the reagents needed to generate reproducible standard curves across multiple sample runs, supporting longitudinal biomarker studies and comparative analyses between patient cohorts.

SLPI concentrations have been investigated as indicators of inflammatory status in chronic obstructive pulmonary disease, cystic fibrosis, and gynecological conditions, as well as in studies of tumor microenvironment and antimicrobial peptide biology. Researchers studying mucosal defense, protease-antiprotease balance, or epithelial innate immunity will find this assay a useful tool for translational and mechanistic investigations.
